Specification of Letters Patent.

lApplication filed'December 3, 1914', Serial-No. 875,271.

To all 'whom 'it may. concern.'

Beit known that 1CHARLEeiTH-aonnn, a citizen of the United Stateso America, and

. a resident of Iront'on, in, the State of= Ohio,

have invented a new and: useful Improvement. in: Bundling-Maehines, ofwhichi the following is a specification.

'llhis inventionl relates tomachines for bundling in lengths; especially 'fon lbundling flooring, siding, lathe,Av box 'shocks' and other like dressed lumber at the millf; toobviate handling the pieces singly in transit from Vplace to'v place.

The present invention consistsin certain novel `combinations of parts, and'. in an improved machine embodying such combinations Aor. any of them, as` hereinafter particularfly described and claimed:

The leading objects of this invention are to provide fon so bundling with wire that the bundles may be elicectively tightened by means'of the wire itself, and witln greater rapidity. and economy 'of' wire than heretofore..

(-)ther objects will lie-set forth in the general description, which lfollow-s:

Three sheets of drawings accompany this specification` as part thereof.

Like reference characters refer to like partsin allthe figures..

Thefimproved machine is an upright built=of iron and steel, sind adapted to be worked by an operator standing before it Patented June 1, '1915.

and using'a pair of pedals, l: and 2; and a. Y.

handv Wheel, 3..

The material for a bundle, a, is assembled bythe operator or a helper vupon ai pairfof horizontal: supports, s, 'and against ai pair of depending. stops 5,-a't the front of thev machine. Eaoliof` said supports 4 is pref.- erably composedfof a knee, fia, rigidlylbolted to one of the front uprights of the'main frame, 6, and av superposed roller'4b; eitheri or both of them adjustable, vertically, to prnvide for. bundling different materiel by ons f and the same machine. Asshow'ii, the' at.- taching bolts passthrough slots, 7", inv the knees 4*, and v-erticalscrews IP-{beneath ther trunnions of the rollers.b render-the rollers independently adjustable for minor Varia tions.

The bundling wire, Z), is .takerdfrom-afreel,

S, at the topot the irameii; said reel being.

preferably telescopic as shown in Fig; l, and.t

thus adapted to have the coil ofl wireeasily transferred `bodily thereto from the shipping spools on which it coines from the wire mill. A horizontale' spindle, 9, having trun n ions at its ends is-movable with thereel 8,

and is remoi-"ably mounted in slotted beanings, 10, Fig. 2. The end disks of thereel rest upon a'steel roller, 1.1, and 'a likeroller, 12, removably mounted in slotted bearings, 13, Fig. 2, rests upon thc upper edges of the reel disks tti-prevent any ypossible escape ofi 90 the wire in coils, andv to obviate keeping the coil compact. The rcel requires no attentionin operating the machine.

The wire b is .fed downward from the reel 8 through the guideway14 of a wire .tightening device through a slide 15 within said guideway and through the spindle member 16 and knife 17 of a wire twister and cutter; and? at the beginning of' eachy bundle operationv the wire b hangsjventically behind the bundle aas represented in Fig. 3.

nections, shown as a whole-in Fig. 2, consisting ot a link, 18, a superjact 'it liver 1.9 fulcrumed in thc frame 6,.:ind a pitma'ii 20; the latter' provided with a weight 2L to-in sure the return of thc slide 15 and its mov Said slide 1'5 is operated by the' main trcadle l through the medium of con-` able appurtenances by gravity to the positions bf rest in which they are shown in Figs'] and il and inv fulllincs in Figs 3` and. 4, with the slide 15 'an tbe botioj oltlfrey guideway 14, and the wire free to be pulled by hand from the reel 8 and wrapped around the bundle alas shown in Figs. 4 and 8,` and in dotted lines in Fig. 9. A main casting, 22, with nwhich the bundle stops 5 are conveniently integral, is common to said wire tightening and wire twisting and cutting devices, and is tixedly riveted in place in the frame 6 at midheight. (Compare Figs. 1 to 4, inclusive.) The principal member of said guideway 14- is bolted fast to and extends above said main casting, and is preferably open in front so as to expose the wire to view within it, as in Fig. 1. It is fitted internally to the body of said slide 15; a rib portion of' which protrudes through a. slot 14h, in the guideway, and is provided with a rigid odset extension 15" to which the upper end of the pitman 20 is bolted. The interior of said slide 15, through which the wire b extends, is provided with a tightening dog 23 pivotede to the body of the slide at one end and constructed at its other end with a clamping face, 23, Fig. 3, opposed to a clamping' surface 15a within the slide, and with a reversely projecting cani portion, 23, Fig.l 3, opposed to the straight face of a. wire-holding rib, Q4, on a guideway cap member 111C; said rib 24 projecting inward through a slot 14d in the body of the guideway, and normally held in place by strong springs 14* compressed between the back of said cap piece and washers backed by adjusting nuts ltt at the outer ends of the bolts 14g. The lower end of said Wire-holding rib 2l is rounded or beveled as represented at 24h in Fig. 3, above a space 25 within the lower end of said slot 14d, into which space said cam portion 23h projects, as in Fig. 3, when the machine is at rest, to free the wire b as aforesaid. The said spindle member A16 of the wire twister and cutter is rotatable in a vertical bore 22a in a, shelf portion 22 of said main casting 22, and has in turn an axial bore, 16, through which the wire .7; extends. (Compare 3 to 9 inclusive and Fig. 13 as to the details ot this device.) The hand wheel, Figs. 1 and 2, is fasten a horizontal shaft, 25, which is mounted in a bearing 22 on said main casting, and is connected with the u pper end of said spindle member 1G by bevel gearing, 2.6, 27. The lower end ofthc spindle member forms a peculiarly recessed and equipped head, 1G", which rotates close beneath said shelf portion QQ of the main casting, and is provided with a pair of tappet lugs, 28, Q9, which successirely engage the faces of beveled teeth, lll), on a parallel tumbler, 16, in the wire twisting and cutting operation hereinafter rti' 'larly described. The lower face 24T-i co tiucted with a transnlar in cross section, 15rs extends. Be-

vcrso i through which. t...

neath this rib the knife 17 slides; said imite having a trumpet shaped wire guide, 17a, in constant communication with said bore lfland forming a wire-cutting edge at its lower end; a socket, 17", adapted to receive y the extremity of the wire preliminary to the twisting operation as in Figs. 1, 2, 4 and 8, and to securely hold the same during that operation; and a notch, 17, within( which said socket 17b is formed.v and which forms a cutting edge for severing the scrap wire. The knife 17 is further constructed with cam extremities, 17l 17e, adaptedv to protrude alternately, and thetumbler 16 is constructed with a matching segmental projection, 32, which engages said extremities 17d 17 successively, and by a rolling action slides the knife 17 back and forth. A last member 17, of the wire twister and cutter, made in common with the knife 17 of tool steel, is attached by screws to the bottom of the head 1G", bein tted internally to said rib 31' and knife 1 and is recessed to form cutting edges, '33, 34,' Fig. 13, ar-l ranged to interact with the opposing edges of the knife at the wire cutting operation; This bottom member 17t is further provided with a rigid linger, 35, which engages the wire b during the first half turn of the spindie member 16 to press the Wire down clear of any edges of the 'spindle head 16b and bottom member '17i with which the' wire might otherwise be entangled. The tumbler 16 turns step by step in bearings formed respectively in the bottom of the shelf 22" and in a subjacent support 36, andthe up per bearing is provided with a com-pressed frictional spring 37, Fig. 3, to prevent its angular d isplacement'by momentum.

Before describing the steps which 1follow i.assembling the material a with the wire'b as in Fig. 3, and drawing the wire forward by hand and passing it upward in liront of the bundle and horizontally across its top, into the end holding socket 17" of the knife 17 as in Fig. 4, attention is called to the way so manipulating the wire is facilitated by thev ample space between the bundle supports 4, as shown in Fig. 1, and by notches, 38, 39, 40, in the shelf. Q2" of the main casting 22, and in the head 1Gb and bottom member 17t of the twister and cutter, which, as best shown in Fig. 4, expose toview the end holding socket 17b and the adjacent portion of thewire b. The operator is thus enabled to quickly insert the wireend, and to satisfy himself that the wire end is in place, before turning' the hand wheel 3. The condition of the wire b and of the wire twister and cu*- tur. with the wire end so inserted as shown in Fig. Ll, is further illustrated by Figs. 6 and which scc. A part turn of the hand wheel 3 next follows, sufficient to give the spindle member 16 and knife 17 a. half turn represented by the arrows a. The siinulta thv CuttingA mig'vs 33, Il
